If refiners entered this huge energy-gathering array to harness ether, they could break the shackles that could only be divided into daytime and night due to different attributes, and harness indefinitely in the array.
Because the essence of divine ether was a completely different kind of energy from the power of the blazing sun during the day and the power of the mourning moon at night.

It was precisely because the Mystic Peaks Palace had such an existence that the Mystic Peaks Academy regarded the Mystic Keep as a training place for developing excellent refiners.
However, due to the limited size of the energy gathering array, only outstanding students in the academy were eligible to enter.
